All Tables

Table 1: Log of the observations. $\sigma _{{\rm star}}$ denotes the standard deviation of flux in images of the guide star during each integration. Column 6 lists the signal to noise ratio of a one-dimensional spectrum within a 1 $^{\prime \prime }$ radius of the QSO.
Table 2: List of emission lines in the galaxy spectrum and the corresponding redshifts. Line fluxes are derived after a correction for Galactic extinction and telluric absorption was applied. Fluxes and EWs are the observed ones.
Table 3: Oxygen abundance determinations. Diagnostics have been taken from following papers: (1) Pettini & Pagel (2004), (2) Denicoló et al. (2002), (3) Kobulnicky et al. (1999).
Table 4: Nitrogen abundance determinations using different diagnostics from following papers: (1) van Zee et al. (1998b); Pagel et al. (1992), (2) Pagel et al. (1992); Thurston et al. (1996), (3) Shaw & Dufour (1995), (4) Kewley & Dopita (2002).
